About this Benchmark

This is a comprehensive benchmark that compares the performance of different combinations of JPA providers
and Database Management Systems (DBMS).
It covers many JPA ORM providers (Hibernate, EclipseLink, OpenJPA and DataNucleus)
and DBMS (MySQL, PostgreSQL, Derby, HSQLDB, H2, HSQLite) that are available in Java.

The benchmark is published by ObjectDB Software Ltd., but it should be useful also for anyone
that is interested only in RDBMS and ORM (and not in object databases).
Please read the FAQ for more details.
